Fire Weather Maps

The Daily Severity Rating (DSR), is an additional component of the Canadian Forest Fire Weather Index (FWI) System. It is a numeric rating of the difficulty of controlling fires. It is based on the Fire Weather Index but it more accurately reflects the expected effort required for fire suppression.
